Abstract (en)

[origin: WO2012085459A1] The invention relates to a conversion device in the onboard network of a vehicle linked on the one hand to a stop-start module (11) comprising a starter-alternator and to a set of super-capacitors (12) and on the other hand to the 14 volt onboard network of the vehicle (13) and to a battery (14). This device comprises at least two differentiated DC/DC converters (20, 21), identical from a hardware and software point of view and disposed in parallel and linked to a supervisor by a communication system, with symmetric wiring at input and output, and means for learning the imbalance in wiring impedance over a predetermined period. The invention also relates to a method for conversion implementing this device.
